 ## 支持芯片
 针对算能系列 RISC-V 芯片的 bsp，包括：
 
-| 芯片名称 | 内存大小 |
-| ------- | ------- |
-| cv1800b | 64MByte |
-| | |
+- 大核
+| 芯片名称 | 芯片架构 | 内存大小 | 默认日志串口 | 备注 |
+| ------- | ------- |------- | -------- | -------- |
+| cv1800b | RISC-V C906 | 64MByte | uart0 | 默认开启 MMU，运行 RT-SMART 模式 |
+
+- 小核
+| 目录 | 内存大小 | 默认日志串口 | 备注 |
+| ---- | ------- | -------- | --- |
+| c906-little | 与大核共享 | uart1 | 无 MMU，运行 RT-Thread 标准 |
+
+> 注：异构芯片需单独编译每个核的 OS
+
+
+## 运行
+
+编译成功后，会在 `bsp/cvitek` 目录下自动生成 `fip.bin` 和 `boot.sd` 文件，其中大核运行文件在 `boot.sd` 中，小核的运行文件在 `fip.bin` 中。
+
+1. 将 SD 卡分为 2 个分区，第 1 个分区用于存放 bin 文件，第 2 个分区用于作为数据存储分区，分区格式为 `FAT32`。
+2. 将根目录下的 `fip.bin` 和 `boot.sd` 复制 SD 卡第一个分区中。
+	- fip.bin：fsbl、 opensbi、uboot、小核运行文件打包后的 bin 文件
+	- boot.sd：大核打包后的 bin 文件
+
+## 驱动支持列表
+
+| 驱动 | 支持情况 | 备注              |
+| :--- | :------- | :---------------- |
+| UART | 支持     | 默认波特率115200 |
+| gpio | 支持 |  |

 ## FAQ
 1. 如遇到不能正常编译，请先使用 `scons --menuconfig` 重新生成配置。
-2. 编译成功后，会在 `bsp/cvitek` 目录下自动生成 `fip.bin` 和 `boot.sd` 文件。

+# c906_little bsp
+该 bsp 为 cv18xx 系列处理器中的协处理器，采用 RISCV C906 @ 700Mhz。
+特性：
+- 无 MMU   
+- 集成浮点运算单元 (FPU)
+
+## Toolchain 下载
+下载 `riscv64-unknown-elf-gcc` 的工具链: [https://occ-oss-prod.oss-cn-hangzhou.aliyuncs.com/resource//1705395512373/Xuantie-900-gcc-elf-newlib-x86_64-V2.8.1-20240115.tar.gz](https://occ-oss-prod.oss-cn-hangzhou.aliyuncs.com/resource//1705395512373/Xuantie-900-gcc-elf-newlib-x86_64-V2.8.1-20240115.tar.gz)
+
+> 注：
+当前 bsp 只支持 Linux 编译
+
+正确解压后，在`rtconfig.py`中将 `riscv64-unknown-elf-gcc` 工具链的本地路径加入 `EXEC_PATH` 或通过 `RTT_EXEC_PATH` 环境变量指定路径。
+
+```shell
+$ export RTT_EXEC_PATH=/opt/Xuantie-900-gcc-elf-newlib-x86_64-V2.8.1/bin
+```
+
+## 编译
+1. Linux平台下，可以先执行：
+```shell
+$ scons --menuconfig
+```
+
+它会自动下载env相关脚本到~/.env目录，然后执行
+```shell
+$ source ~/.env/env.sh
+$ pkgs --update
+```
+更新完软件包后，执行 `scons -j10` 或 `scons -j10 --verbose` 来编译这个板级支持包。或者通过 `scons --exec-path="GCC工具链路径"` 命令，在指定工具链位置的同时直接编译。编译正确无误，会产生rtthread.elf文件。
+
+编译完成后脚本自动调用 `combine-fip.sh` 脚本进行打包，并生成 `fip.sd`, 该文件即为 SD 卡启动的 c906_little 文件。
+
+
+## 运行
+1. 将 SD 卡分为 2 个分区，第 1 个分区用于存放 bin 文件，第 2 个分区用于作为数据存储分区，分区格式为 `FAT32`。
+2. 将根目录下的 `fip.bin` 和 `boot.sd` 复制 SD 卡第一个分区中。后续更新固件只需要复制 `fip.sd` 文件即可。
+其中：
+- fip.bin：fsbl、 opensbi、 uboot、c906_little 打包后的 bin 文件
+- boot.sd：大核打包后的 bin 文件
+
+更新完 `fip.sd` 后， 重新上电可以看到串口的输出信息：
+```shell
+HW_HEAP_BEGIN:83f74dc0 RT_HW_HEAP_END:84000000 size: 569920
